To all whom it may concern:

Be it known-that Fnnnnonx F. RAYMOND, 2d. late of Newton. inthe countyof Middlesex and State of Massachusetts, deceased, invented certainImprovements in Blank- Holders for Heeling-Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification. like reference characters on the drawings indicatinglike parts in the several figures.

The present invention relates to heel attaching machines and moreparticularly to the blank holding and carrying devices for suchmachines.

In i nited itatcs Letters Patent No. 1,009,710, grant (1 November 21,1911, upon application Serial No. 422,320, filed February :0. 1892; ofwhich the present application is a division. there is disclosed a heelattaching machine comprising a shoe support and a rotatable andreciprocatory turret having heel nailing and top lift spanking devices.11 that .machine the top lift carrying and spanking device is mountedfor pivotal movement from a vertical receiving position in the rear of ashoe on the support to a horizontal spanking position in alinement withthe heel previously attachcd.

It is an object of the present invention to provide a top lift holder orcarrier Which may be advantageously employed in heeling machines whichoperate in this manner, although the improved top lift carrier hereindiscloscd is not limited in its use to this particular type of machinebut may have general application.

A further object of the invent-ion is to provide an improved top liftholder and carrier of such construction that top lifts may be readilyplaced therein and firmly held by the carrier and transferred intoattaching position without displacement, regardless of varying thicknessor dimensions.

It is of particular importance that a top lift should be presented tothe shoe in accurate alinement transversely thereof as the top lift iscommonly used as a gage for subsequent. trimming operations on the heeland a slight inaccuracy in contour transversely of the shoe would beconspicuous in the finished article. It is also important for similarreasons that the top lift should be presented in the proper angularrelation.

With these conditions in' View, an important feature of the inventionconsists in the provision of blank clamping members comprising a breastgage arranged for yielding movement toward and from a back gage, the

latter being capable of transverse adjust-- ment. Such construction notonly permits accurate transverse positioning of the top lift but also,on accountof the pressure of the breast gage, tends to center the liftif the latter is inserted in an incorrect angular position.

Important advantages incident tov the employment of a longitudinallyyielding breast gage in combination with a longitudinally fixed backgage are that the top-lift will be accurately located with respect tothe rear end of the heel and that it will be moved automaticallyrearwardly in the holder into engagement with the back gage regardlessof its position when inserted by the operator.

In operating 'heeling machines it is desirable to locate the rear curvedsurface of a blank accurately with respect to the corresponding part ofthe heel seat or heel and permit variations in the length of the blankto be taken care of at the breast-edge, from which surplus stock isremoved in a. subsequent breasting operation. If the rear end of the toplift is not located accurately the inaccuracy is transferred in amagnified and conspicuous form to the finished heel.

Other advantages of the improved blank holder and carrier will be bestunderstood and appreciated from the following description, togetherwiththe accompanying drawings. in which, v I

The top lift clamping ceiving position.

The machine frame comprises two vertical side portions a, a, and a crosstable a which is formed integral with the side pieces. The turret of themachine is mounta transverse shaft B, journaled in boxes 6', mounted forreciprocation in the guides 6 attached to the upper end of the sides ofthe frame. nected by a transverse bar B" which, with the turret,constitutes the cross head of the The ends of the shaft B extend throughthe boxes and are engaged'by the upper ends of the connecting rods C,which- .connect the shaft with the cranks c of the crank shaft. At oneend of the shaft? is a disk I) which carries cam rolls 6", these camrolls being arranged to travel in cam tracks in a stationary cam plate6". The cam plate is provided with suitable switches which cooperatewith the rollers and cam tracks in such a manner as to cause theautomatic rotation of the turret to present successively in operativeposition the various instrumentalities carried by the turret.

The turret is shown as provided with four arms d, d, d d of which thearms (2, cl, carry a yieldingly mounted perforated nail teniplet'dadapted to carry a loaded heel blank into attaching position, 'and.

drivers d arranged similarly to those described in said Patent No.1,009,710. The arms d, d, are provided with spanker plates or blocks d,and top lift clam ing members are carried by each of the spanner blocks.

The cross bed a supports a jack comprisa work support a mounted thereonand a sleeve e for supporting the spindle. The'sleeve 6 projectsupwardly from a base plate e slidin movement by wa s'formed on the crossed a in order to aci-litate the operations of supplying andnremoving ashoe from the jack. The shaft journaled in the side ieces of the frameis rovided with a suitab e driving pulley and is connected throughsuitable gearing with the crank shaft. A treadle f and clutch mechanism(not shown) are rovided for controlling theoperat-ion of tie machine.Preferably,

this mechanism may be arranged to stop the machine with the cross'headin its highest position and to prevntits descent until it is desired tostart the machine. i

All of the parts above described may be similar to those disclosed insaid Patent N 0. 1,009,710 to which reference may be had for furtherdetails of construction.

receiving position the top lift carrier occu-' pies a vertical positionabove and at the rear of the shoe on the work support. A carrier in thisposition is shown on the right of Fig. 1, the top lift T having beeninserted.

The breast gage breast engaging portion 11. which extends transverselyacross the lower portion of the surface of the spanker plate andisyieldingly held against downward displacement. To this end it may beformed as an angular piece with the portion [i extending over the bottomedge of the plate at, the carrier beingin vertical receiving position,and hav ing a tubular projection or sleeve it slidingly received in therecess h. A spring It attached to the inside of the sleeve and to a capwhich closes the upper end of the recess 72. acts to draw the breastgage longitudi' nally of the sp-anker plate, its movement be ing limitedpositively in an upward direc' tion by the engagement of the portion 71.with the edge of the spanker plate. The sleeve [2, guides the breastgage, holdin it in contact with the surface of the spaniel plate andpreventing twisting. The back gage is mounted at the other end of thespanker plate. and comprises a plate it having a concave or ll-shapedrecess to fit the curved end of a top liftf The plate 71 is capable oftransverse spanlrer plate (1? and to this end may be pr0 vided withslots it through which project screws or studs. h from the spankerplate. The back adj ustm'ent .on the comprises a straight ge maylie-adjusted transversely on the stu s h to position a blankproperly onthe spanker late. I v

A blank may e inserted in the carrier by pressing its breast edgedownwardly against the breast gage it, displacing the gage against thetension of the spring 71. enough to permit the roundedend of the blankto he slipped into the recess of the back gage. When this is done theblank will be clamped against the surface of the spanker plate betweenthe two gages and it will be securely held in such position while thecarrier is moved in a vertical arc, longitudinally of the shoe, fromreceiving'posiring position over the previously attached shoe; ingoperation is then effected by Ward movement of the cross forces the toplift on the ends left projecting 'fromthe heel. The subsequ ent upwardmovement of the cross head draws -thecarrier off the attached top lift.It will be seen that the improved carrier herein disclosed maybe veryconveniently supplied with blanks since, in its receiving position, itoccupies a vertical position in head which ofthe nails .Th?L spankwhichit may be readily seen and-is within reach of an attendant standing atthe rear of the machine. The act of inserting a blank is also efiectedeasily and naturally by depressing the breast gage as above ex-,

plained. Moreover, if a blank is inserted in an incorrect angularposition the pressure of the breast gage on one corner or the other willact to center the blank, turning it into theproper position assoon as itis re leased by the attendant. It will also be seen that each'blankpositioned with its rear curved surface in a predetermined position,ditferences in length being taken care of by the' yielding movement ofthe breast gage.-
